 species occurred in the Fire-Hole Basins in great abundance, but with 

 leaves and stems so black as to be scarcely recognizable. "The pedun- 

 cles are shorter, and the lobes of the corolla more strongly lacerate 

 fringed than usual. It approaches G. crinita, with which it is probably 

 identical." Professor Porter.

 are shorter and the lobes of the corolla rounded, very obtuse, and occa- 

 sionally furnished at the base with a few small teeth." Professor Porter.
